Discussion
Assertion (A): A canard layout can protect its main wing from stalling.
Reason (R): The foreplane is designed to stall first and drop the nose automatically.
Select the correct answer from the options below.
Answer: C
Correct answer: Both A and R are true, and R is the correct explanation of A
Both are true and the second is how the protection works. The foreplane is sized and set so it reaches its stalling angle before the main wing.
When it does, its lift falls, the nose drops and the angle of attack reduces automatically, so the aeroplane cannot be held beyond that point whatever the pilot does with the stick. The main wing never stalls, and the classic wing drop is avoided. It is a designed-in limit rather than a warning device, which is what distinguishes it from a stick pusher.
